[Prior technology] The short-wavelength ultraviolet rays are widely used in the decomposition of harmful substances or organic substances because of their high-intensity energy. In particular, ultraviolet rays with a wavelength below 240 nm dissociate water (水? 0) and generate them. The fluorenyl group is decomposed by photoreaction of organic matter used in water. One example of the reaction formula is shown below: H20 + h —Η + 0Η group CnHmOk + 0Η group — CO, C02, Η20 (η, m, k, is 1,2,3…) In the above reaction formula, the OH gene generated by the dissociation of water has strong oxidizing power, so it can decompose organic substances existing in water to generate C0, C02, H20 and so on. In other words, the short-wave ultraviolet (i.e., ultraviolet light) hv below 24 Onm is the energy to generate 0H radicals. The ultraviolet light source radiating ultraviolet rays below 240nm is a low-pressure mercury vapor discharge lamp, which is generally familiar. Low-pressure mercury vapor discharge lamps, whose luminous tubes (ie, tubes) for ultraviolet light emission are usually made of quartz glass. A pair of filaments are installed at both ends of the luminous tube, and rare gases such as ya (Ar) are enclosed in the tube. (Inert gas) and an appropriate amount of mercury (mercury). When a discharge current is supplied to the filament of one of the discharge lamps, a short-wavelength ultraviolet light of 1 85 nm specific to mercury can be emitted from the light-emitting tube.

Description of the invention (2) Organic matter mixed in water undergoes photoreactive decomposition. The above-mentioned low-pressure mercury vapor discharge lamp has been used for ultraviolet radiation to produce, for example, semi-finished products or finished products in semiconductor manufacturing processes; ultra-pure water that is used in large quantities for washing water. In this case, since the object to be processed is a liquid, the processed object and the unprocessed object cannot be digitized like a solid object. In addition, '' is a continuous flow. Therefore, the liquid of the object to be processed must be continuously irradiated with ultraviolet rays. Ultraviolet devices used in such an environment have extremely low operating costs, improved productivity (k South of the processing efficiency of the liquid being processed), and environmental protection requirements. Therefore, the industry has strict requirements for energy saving, maintenance, and resource saving. The requirements are very high. Effective means to achieve the above requirements can extend the life of the discharge lamp. However, the above-mentioned ultraviolet irradiation device needs to continuously irradiate the liquid to be processed continuously, so the 185nm short-wave ultraviolet light output by the discharge lamp will be reduced by half after one year. Therefore, the discharge needs to be discharged every year. All the lamps are replaced together. Such regular maintenance and disposal of used discharge lamps are inevitable. The inventor 4 has considered that the discharge of the short-wave UV light at 185 nm decreases over time after use of the discharge lamp. After conducting various experiments and analyzing the results of the experimental data, it is found that the main reason for shortening the life of the discharge lamp is to form a light-emitting tube Tube) of quartz glass. The material of the discharge lamp used in the above-mentioned device is a quartz glass made of fused silica glass using natural crystal as a raw material. This quartz glass contains impurities of several ppm, such as sodium (Na), potassium (K), titanium (Ti), and iron (Fe), which particularly absorb ultraviolet rays.

[Summary of the Invention] The present invention is to improve the maintenance rate of the external line output of the discharge lamp 1 which emits ultraviolet rays below 24nm, to provide continuous operation that can withstand long periods of time, and an ultraviolet irradiation device that can truly achieve the goals of maintenance and resource saving, and Its application. Method. 2. The ultraviolet irradiation device of the present invention provided to achieve the above-mentioned object is provided with: a synthetic 1-inch glass light tube (lamp tube), a discharge lamp capable of radiating outside lines of less than 24 nm, and a lamp capable of emitting the discharge lamp. Ultraviolet rays are irradiated to the processing device of the continuously processed liquid. Accordingly, as will be described later, when the above-mentioned discharge lamp is used, a fluorescent tube made of synthetic quartz can emit ultraviolet rays below 240 nm, so it is possible to suppress the decrease in the ultraviolet transmittance of the ultraviolet rays and improve the maintenance rate of the ultraviolet output. Therefore, the processing device can be continuously irradiated with ultraviolet rays for a long time to the continuously processed liquid. This lengthens the period of regular maintenance, and achieves provincial maintenance and lengthens the disposal period of used discharge lamps.

The discharge lamp 30 of this embodiment is a discharge lamp capable of emitting ultraviolet rays in a short-wavelength range of less than 24 nm, and the light-emitting tube 11 for ultraviolet light emission is made of synthetic quartz glass. The size of the fluorescent tube 11 of this discharge lamp is 15 mm in outer diameter, the wall thickness (tube wall thickness) is 1 mm, and the distance between a pair of filaments 2 1 a, 2 1 b is 1 5 3 cm. An appropriate amount of mercury (for example, about 20 mg of mercury) and a rare gas of about 400 Pa are enclosed in the light-emitting tube 11. When a discharge current of Αα is connected to the discharge lamp 30, the power of the discharge lamp becomes MOW (watt), and about 5% of the energy can be output as ultraviolet light of 1 85nm to the outside. This ultraviolet output is approximately equivalent to about 1 of the size of the light-emitting tube, the distance between the lamp and the filament, the enclosed amount of mercury and rare gases, and the electrical conditions. · 5 times. Therefore, the ultraviolet radiation efficiency of the discharge lamp 30 of this embodiment is obviously higher than that of the conventional technology. The discharge lamp 3 shown in this embodiment is a tube with an outer diameter of 15 mm, a wall thickness of 1 mm, The discharge current is 1A. The ratio of the outer diameter of the tube to the thickness of the wall is preferably set in the range of 0.1 to 0.04. This range is determined by the correlation between UV absorption and the absolute strength of the machine. In addition, the discharge current density (discharge current per unit area in the tube) is preferably in the range of 200 mA / cm2 to 800 mA / cm2, which is related to the luminous efficiency and economic efficiency of ultraviolet light at 185 nm. That is, when the current density range is deviated from the above, the conversion efficiency of ultraviolet rays converted from 18511111 during discharge will be drastically reduced, and the use of expensive synthetic quartz glass will lose its meaning. The reason why the ultraviolet output of the discharge lamp 30 of the present invention is higher than that of the 'discharge lamp of the prior art' is explained below.

For example, the above-mentioned impurities in synthetic quartz glass are 1 / of the general molten quartz glass. 10 or less. When the discharge lamp 30 of the light-emitting tube 11 made of such synthetic quartz glass is used, the light-absorbing tube 1] L tube wall has less ultraviolet absorption than the conventional technology, and has excellent short-wavelength ultraviolet transmittance characteristics. . Therefore, not only the intensity of ultraviolet rays (ultraviolet radiation intensity) in the initial stage of use is high, but also the deterioration with time (deterioration and deterioration with time) caused by the cycle of absorption of ultraviolet rays and the deterioration of quartz glass itself can be suppressed. Therefore, the ultraviolet light output of 185nm in the short-wavelength range can be maintained for a long time, and the durable life of the discharge lamp is greatly extended. Even when the ultraviolet irradiation device of the discharge lamp 30 described in the above embodiment is used, the long life of the discharge lamp 30 makes it possible to eliminate the trouble of replacing and maintaining the discharge lamp 30 every year without having to use the discharge lamp. 30 Disposal, to achieve the effect of saving man-hours and resources.
